Recent problem with my parents' LG FD, about 5 yrs old I'd guess: Makes ice fine but then it seems to melt and refreeze, ending up with about 1/4-1/2 inch frozen solid at the bottom of the tray and then cubes on top of that, though they are fairly stuck together also.

My guess offhand is that the defrost is working "too well" but I'm wondering if there's any possibility of user error. In case it matters, one thing I've noticed they do is let the bin fill up and then shut off the icemaker until they've used up all the ice.

Suggestions appreciated. TIA!
